Difficulty settings added.

Players will now have to choose between two difficulty settings (hard and easy) when starting a new game.

Hard is the way the game is meant to be played. Deaths are permanent and you'll have to start from the beginning if everyone dies. However this is a very unforgiving and ruthless way to play the game. Some players might find it a bit too tedious to have replay every level after their party got wiped. So now there's the easy -option. In easy -mode you'll get a checkpoint at the start of every level just like on the hard -setting but this time the game remembers who's alive at the start of the level. If everyone dies you can simply return to the previous checkpoint.

I hope everyone can now enjoy the game the way they prefer.
